VIDEO: 3 wanted for brutal beating of Bronx boy

A 14-year-old boy was attacked while he was waiting for an elevator in his Bronx apartment building by three punks — including one who recorded the beating on his cellphone, cops said.

Surveillance footage from within the Eastchester building shows the heartless assault play out around 2:30 p.m. Monday as two of the thugs sneak up behind the unsuspecting victim.

But they wait for their cohort to get close and begin filming before they attack.

They punch him and throw him to the ground. They then kick him as he lay helplessly.

Then the third suspect jumps in and repeatedly stomps on the boy while the two other attackers are seen fleeing.

The trio steal the victim’s sunglasses and sneakers. He was taken to Jacobi Hospital where he was treated and released.

The suspects are described as being between 16 and 20 years old.
